rebase: mention phases in the help
Mention that Mercurial helps you not do what you've just been warned not
to do, with a reference to the 'phases' help topic (not the 'phase'
command help).
Thanks to Pierre-Yves David <pierre-yves.david@ens-lyon.org> for
motivating this change and Wagner Bruna
<wagner.bruna+mercurial@gmail.com> for advising on how to do it in an
i18n-friendly way.
